Not sure how to tag spoilers so I'll keep it very vague but don't read more of you're not at least level four and have explored most of the accessible map to that point. Anyway there's a fight in the first act where a VERY BOSS-LIKE creature is supposed to allow you to take control of him, help in the fight and middle his health down and THEN be killed.

First time he doesn't say anything til halfway through beating me to a pulp and then after I successfully take control of him he STILL KEEPS AGGRO on me and does absolutely nothing. Still almost managed to beat him, died after getting him down to one health and getting critically hit on his last attack - thems the breaks.

I re-load, reposition and strategize for the fight, do much better and this time....he never says anything or prompts any dialogue* even though I specifically avoided aggroing or doing any damage to him whatsoever. Managed to beat his ass anyway, but still...the game (while great fun) is glitchy and so far many encounters don't go the way they're supposed to.
